Cross seas: Nature, or design?

Here’s just exactly the sort of thing that happens in nature that drives creationists nuts. How could this happen without God personally working to confuse and/or delight the photographer? Not to mention the physicist and mathematician.

Where? Somewhere in France, one might gather from the flag on the structure (lighthouse?).

Crossing swells, consisting of near-cnoidal wave trains. Photo taken from Phares des Baleines (Whale Lighthouse) at the western point of Île de Ré (Isle of Rhé), France, in the Atlantic Ocean. The interaction of such near-solitons in shallow water may be modeled through the Kadomtsev–Petviashvili equation.

Oh, you remember that one, don’t you? The Kadomtsev–Petviashvili equation?

At least we confirmed it was taken in France.

They do everything differently in France, don’t they?

Update:Got an e-mail suggestion that I include the equation itself. You may certainly click to Wikipedia to find it; here’s what it says over there:

where . The above form shows that the KP equation is a generalization to two spatial dimensions, x and y, of the one-dimensional Korteweg–de Vries (KdV) equation. To be physically meaningful, the wave propagation direction has to be not-too-far from the x direction, i.e. with only slow variations of solutions in the y direction.

What would you expect to see if the designer is intelligent? Him splashing his feet in the water? Or maybe more likely you’d expect a system so complex that it created the longest math formula in bathtub history to even understand it.

Dead Link?

We've been soaking in the Bathtub for several months, long enough that some of the links we've used have gone to the Great Internet in the Sky.
